I need to know the right temperture settings cause i dont have a manual


dont try to lower cool setting below 70 degrees or heat setting above 78 degrees. all a/c's are designed for a 95 degree ambient when it gets above that you have to increase tonnage to compensate.

I am trying to lower my temperature to cool my house but it will not go any lower than 78, is there anything i can do to reset or lower the temperature?


Hi,
Many t-stats will not let you go within less than 2 degrees of the heat set point....

Lower the heating set point and then you will be able to lower the cooling setpoint..

Can somebody help,why is my Central AC blows


Most heat pumps have an auxillary heat. Many are electric auxillary heat with a heat strip in the air handler. A common malfunction is for the electric auxillary heat to operate when the heat pump is set on cool. To confirm this, locate the conductor that runs from the heat sequencer to the connection on the heat strip. You will see this on the top section of the air handler. Use the clamp on part of the amp meter over that wire. If the thermostat is set on cool and the heat strip is drawing amps, it means the heat is coming on while the heat pump is set on cool. There is usually one or two causes for this, either the sequencer is bad or there is low voltage wires usually behind the thermostat or in the air handler closet that are touching that shouldn't be touching.

If this is not the case, if its not a problem of where the heat is coming on with the air conditioner, it could be a case of the reversing valve malfunctioning. The way a heat pump works is it reverses the flow of the refridgerant. For instance, many heat pumps the reversing valve is activated in cool. That would mean that there is a low voltage circuit that activates the reversing valve when the heat pump is in cool. I'm not sure what model/brand your heat pump is, Goodman and Janitrol for instance, the heat pump reversing valve is activated in cool. In any case, if the reversing valve is not operating properly, when the air conditioning is set to cool it will actually be heating. Or you could set it to heat and it may actually be cooling instead of heating. Please check these two items first and if you have any further questions, please let me know. Especially if you know of any additional problems like the evaporater is icing up or if the air handler fan is not operating when it should.

Can not get temp below 77


Is the thermostat set up for automatic change over from heat to cool? If so, the heat is probably set for 75, you will need to lower the heat setting in order to Lower the cooling. the stat won't let these settings with in 2 degrees of each other so the heating and cooling don't fight each other.

Fan is blowing but air is not cool, outside pumps


If I understand you have two units one top and one bottom. If one is not running you have a problem. It will cause the other unit to work harder. Check breakers and the basic things. But you may need to call a service tech ask for free estimate. Russ

Need to know what the settings are for the range adjustment A,B,C,D slide switch on the front panel on a Amana PTH123A35AC PTAC


Here they are;

Position A, Cool 70-78, Heat 65-73
Position B, Cool 68-81, Heat 68-76
Position C, Cool 66-83, Heat 61-78
Position D, Cool 63-88, Heat 58-83

Amana calls this a Temerature Limiter and says to only set one switch on at a time. If all switches are off then the unit is at full operating range.
Please rate this answer to let me know if it was the fix.
